How to execute a globally defined MEL proc from Python/pyMel?

[Alan Fregtman]

Hey guys,

I sense this is a really really noobish question. I apologize if that is so.

There's a global proc defined in a loaded .mel script (from a third
party) which I would like to call from my Python script in Maya.

I tried something like this:
import maya.cmds as cmds
cmds.SomeGlobalProc(arguments...)

and it didn't work, so I assume that cmds is only for original Maya
commands and not globally defined mel procedures, so... what's the
right syntax?

Any help appreciated.
Cheers,

-- Alan

I think you need to import the maya.mel module in order to be able to run the eval mel command, passing the syntax of the mel procedure as a string:

Mel code to run:
myFuntion($var1, $var2)

Python syntax:

import maya.mel
maya.mel.eval('myFuntion(argument1,argument2)'

I don't know if there is a better/other way. Hope it helps.

There was a parenthesis missing in the python syntax above:

Valid code, passing the mel procedure with C style syntax:

import maya.mel
maya.mel.eval('myFuntion(argument1,argument2)')

or

import maya.mel
maya.mel.eval('myFuntion argument1 argument2')

Perfect! Can't believe I didn't think of "eval()".

Thank you, Charlie.

I little bit cleaner, in my opinion, to use it like this:

from maya.mel import eval
eval( 'myGlobalProc();' )
